AGES Rheocasting Initiative

As the casting industry is changing rapidly due to higher demands from designers, we at AGES have concluded that we need to add semi-solid casting to meet our customers’ requirements and we see this as a complement to our HPDC production.

The alloy

Low Si, 190-200 W/mK (120 W/mK for HPDC).
Thermal treatment increases thermal conductivity.
New alloys in R&D platform for 2019–2023.

Benefits with rheocasting

The process offers several benefits such as:
• Alloy freedom as a wider range of alloys are castable with rheocasting than with HPDC.
• Very low porosity levels that open up for leak-free, weldable and heat treatable components.
• A cost-effective process that allows the production of components to a reasonable cost.

Application: cooling

Geometry and design.
Fins: 105 mm and 0.8 mm at tip.
Low draft angles: 0.4-0.6 degrees.

Application: pressure tight

Status: DV´s passed and production starting 2019, leak free components without impregnation, from 15 bars to 120 bars of pressure.

Technical

Impregnation is often not possible for high pressure, high temperatures and cost.
